The receiving setup has been moved and is thus hard to review.
Nothing really changed, except for this section which I removed in the PR.
The comment is true. There are useless interrupts, however the driver handles them just fine.
When I put this here 4 years ago, it's likely I was confused. The driver is fine, but my code back then likely wasn't.

| - Add TX continuation (into RX state) for fast tx-rx turnaround time | ||

| - Add support for 'raw' messages (aka it's up to the user to encode them as valid ieee 802.15.4 frames) |

For fast turnaround times we need some hardware acceleration support.
This PR introduces continuation after TX so the radio can go to RX mode immediately after it is done with transmission.
I've chosen to not incorporate this into the typestate mechanism because all the combination of options would explode the number of variants. After the TX is done, the user needs to call the appropriate continuation function or get a runtime error.
The auto acks are simpler and are pretty much just turned on and off.
